SELF-RETAINING CASTER SOCKET FOR ANGLE-IRON LEGS.

Application filed May 26,

To Il viii/10m, t mayV concern.'

Be it known that I, VILLIAM H. Nonni*- ING, a citizen ot the TJnited States, and a resident ot Evansville, county ot Vander- 6 buigand State of `indiana, have invented a certain new and useful Self-Retaining Caster Socket for Angle-Iron Legs; and I hereby declare that the following is a full, clear. and exact description thereof, reference being had to the accompanying drawingsin which like numerals refer to like parts.

This invention relates to acaster bracket socket 'tor angle iron legs A'which are usually found upon washing machines and the like.

The chief object of the invention is to construct a bracket which will ciainpingly engage the lower' end of an angle iron leg to be securedthereto and which will supper-t said leg` upon a caster bv means of a socket arrangement which may be detachable or integral with the bracket.

The several features ot the invention are as follows:

)i metal bracket having parallel and oppositelvY turned clamping` lateral edges for engagement with the angle iron longitudinal edges.

.. wedging engagement associated with "i" each :ingle iron edge.

A lateral support or ledge and preferahlvunder the end of each angle iron side.

."'rn upturned flange to form a socket with l the supporting ledge above noted.

.k support for yieldingly supporting and 'etaining the caster in the bracket.

)au arrangement for limiting the inward movement of the caster.

A ln several instances a clamping engage- -i0 ment with the caster or caster socket.

ln several instances a triangular base plate having a caster stem receiving opening therein which is positioned so as to secure a. predetermined relationship between i5 the caster stein or socket supporting the saine and the walls oi the angle iron leg.

The Jfull nature of this invention will be understood 'trom the accompanying draw.-

` and the following description and :30 claims.

Fig. 19 is a. top plan view of a modied torni of vthe invention and is very similar to that shown in Figs. 'i' vto 9 inclusive. Fig. 2O is a top plan vien' oi a modified form of the invention and is very similar to that shown in Figs. 13 to 15 inclusive. F 2l is a top plan view of a modilied torni of the invention and is very similar to that shown in Figs. 1G to 1S inclusive.

rlie invention relates to a bracket adapted to be secured upon an angle iron leg and vieldingly retain a caster which, under load through the bracket, supports the leg. This invention is another type, but serves the same purpose as the caster bracket socket shown in the prior Patent No. 1,383,773.

In Figs. 1, 2 and 3 one form of the invention is illustrated, and this form ofthe invention is shown mounted upon an `angle iron having the sides 2O with longitudinal edges 21 and ends 22 and the central angle or edge 23. The caster may be of the usual type and herein such a caster is illustrated as comprising a yoke or base 24 which supports a pintle or stem 25 herein shown as having a curved head 26 and a reduced neck portion 27. A fiange 28 assists in securing the yoke to the stem, but any form of caster might be utilized except as will be hereinafter noted.

Extending in a plane beneath the end 22 is a base 30 which has forwardly projecting portions 33 which constitute ledges adapted to support the end of the leg.. These ledges may, or may not, terminate in a plane parallel to the outer face 2O of the leg side, but herein such ledge is shown extended at an angle tothe sameas at 34, and this angle may form a gradually tapering groove if desired, which loses its taper when the leg is received thereby, or the flange 34 may extend upwardly in parallel relation to the side 20. Thus a wedging or clamping engagement with said side may be secured. The base 30 is substantially triangular in shape and two sides of said triangle are provided with forwardly project` ing ledges 33and the up-turned retaining flanges 34. The third side or base of the triangle is provided with an rip-turned back 35 which extends across the angle of the angle iron and each end of the back 35 is extended at 36 to lie parallel to the longitudinal edge 21 of the leg and at right angles thereto. The extension 36 is further extended at 37 and this in turn at 38, each beine` at an angle to each other to form a b 1D clamping groove, which groove is adapted to receive the longitudinal edge 21 of the angle iron. As shown clearly in Figs. 1 and 3, and indicated by the numerals 39V in said figure it is noted that the grooves are inclined towards each other as they approach the base, thereby insuring a wedging or clamping action when the bracket is inserted on the end of the angle iron, or pressure oi' weight is applied thereto. All of these several features are common to substantially all forms of the invention except that shown in Figs. 10, 11 and 12.

The back 35 is extended outwardly and forwardly as at 40 to form a cap or top adapted to engage the top of the head 26 of the stem 25 and limit the inward movement of the stem. This overhead extension 40 is turned downwardly and inwardly as incheated at 41 to provide a tongue for engag,

ing the neck 27 of the stem 25 to yieldingly retain the caster stein in the socket. Thus, a frictional yielding engagement is formed by the forward extension 40 and the tongue portion 41 to retain the stem in the socket.

The base 30 is apertured as at 42 and a flange 43 defines said opening and isl formed from the metal constituting the opening.V The back 35, as shown clearly in Fig. 1, is herein shown adapted to lie substantially parallel to and have a linear engagement with the stem 25,'and the tongue 41 maintains the stem in upright relation against said back.

In Figs. 4, 5 Vand 6 a slightly modified Y These fingers are formed. by slitting the back 35 at 145 and then turning the projecting portions forwardly fand in a curved relation so as to form a cylindrical, or if the caster stem is not cylindrical, a tubular socket which embraces the body portion 25 of the stem. The relationship hereinbefore described with reference to the tongue 41 and back plate 45 when associated with the stem 25 in this modified form of the invention is the same and in addition there is provided the two clamping socket forming members. i

In Figs. 7 8 and 9 another and modified form of thel invention is illustrated and herein the similar parts are indicated by similar numerals of the 200 series. Thus. the base plate is indicated by the numeral 230, the supporting ledge by 233, the foi'- ward rip-turned flange by 234, the back by 235, the inner side of the lateral groove by 236, the'base thereof by 237 vand the front face thereof by 238 and the taper or wedge relation is shown at 239. Extending forwardly from the back 235 is the overhead projection 240 which is adapted to engage the upper end of the socket, which socket in turn is adapted to receive the caster stem.

The socket, as shown by the dotted lines in Figs. 7, 8 and 9 includes the substantially tubular body 250 havinga closed end 251, preferablyv semi-spherical in form, and two parallel lianges 252 and 253 positioned upon opposite sides of the hase plate 230 rigidly securing the socket 250 to the bracket and in the opening 242. The lower end of the socket is illustrated as open and'adapted to receive the stem of the usual caster construction. Thus, the overhead oi' forward lateral projection 240 is adapted to clampingly engage upon the socket 250 and force the same into alignment so that it will maintain a vertical relationship with respect to the base plate 230, and herein such a relasuitably slit at st'- tionship is secured byl means ofthe back 23 ot the angle iron.

ln Figs. 10, 11 and v12 a moditiedfiform of the inventionis'illustrated. In this form oit the invention similar partsfof the bracket areV indicated by numerals of the 300 series. Herein the lateral supporting ledgesare indicated bythe numeral 333, the rip-turned- Vilaiiges associated therewith by 334.' AThe inside ot' the groove construction engagingf the Vlongitudinal edge 21, is indicated by the The base thereof is indicated..

These lingers trictionally en- -gage the socket 250 and yieldingly vretain *the-.same upon the b 1acket when the socket is removed from tli-e caster stem.- inward 'movement or the socket, as previously described, is limited by the flange Q53 engaging' the base 130. The socket, therefore, is ii'iaintained in vertical alignment with re* spect to the base 430 by the fingers 44A and the back lt desired, the nngers may be shortenedr so that they are not interposed between the socket and the inner wall of the sides 2O otr the angle iron and, then'the socket will lie directlyagainst the angle iron. n

In Figs. 16, 17 `and 18 another modilied form ort the invention is illustrated, and in thisfoiin of the invention the socket 250 inv stead of being provided with two parallel `flanges or enlargements 252 and 253, is provided with one flange enlargement and a pair of enlarged portions 254, substantially equivalent to the circularilange 252.' lith these enlargements, however, the socket 250 is Iadapted to lie adjacent the inner.` angle .walls ofthe side 20. In'this form ot the` invention the backfp'late 535 extending upwardly from the `basel 530, and angularly across theangle iron' yieldingly forces the socket into engagement with said inner angle side wall by engaging' the opposite and ,intermediate point of the socket. This form ott the bracket is provided with' the usual forwardly supporting ledge 535 with the up- .turned flange 534 and the back 535`is provided with the extension 536 whieliforms a portion of the groove, the base of which is indicated by the numeral 537 and the-forward portion of which is indicated by the numeral 53S. This groove yalso has a wedging or clamping engagement, as indicated at l539. The base 530 is apertured at 542, and

as shown in this forni of the. invention no additional means is necessary to retain the socket in the bracket except the enlargements 253.

lnV Fig. 19 there is illustrated a further modified form ot' the invention and in this form the bracket- 635 extends from edge to edge of the angle iron leg and the extension 637 with the inward extensions 633 term the clamping construction substantially similar to that. shown in Figs. 7 to 9 in* elusive. The bracket is provided with a top plate 640 and a bottom plate 630, which bottom` plate is extended `at 63st to form upwardly extending retaining members. In Fig. 2O there is illustrated another modified form ofthe invention which is substantially similar tothat disclosed in Figs. 13 to 15 in- Herein the back 735 extends from edge to edge of the angle ironand-the extensions 737 with'the inward extensions 7 38 lil() llt) forni the clamping construction. The baise o supports the socket 7 42 and said base is D 'further extended to provide thefupw'ardly ioA 'ext-ending portions 734. The-inwardly ex-A tending curved iingers 744 formed from the back 735 are adapted to frictionally retain the socket member 742. The foregoing construction is substantially similar to that particularly illustrated in Fin: 15. j A

in rig'. 2i a fun-her moinea form of the invention is illustrated which is rsubstantially similar to that shown in Figs 16 to 18 inclusive. In this form ofthe invention, the back 835 extends from edge to edge of the angle iron and the extensions 837 provided with further inwardly extending' extensions 838 constitute 'the clamping' construction.

The base 880 is provided with an aperture to receive the socket member 250 for the en iar ements 254 which rigidly secure said Y forms illustrated in Figs. 1 to 6 inclusive fand 10, 11 and 12 the socket is formed integral with the bracket and lmay detachably but yieldingly support the caster stem. The `caster socket 250, which is detachably or rigidly associated with the bracket as desired, supports the caster stem ,in any desired or preferred manner.
